INSIDE LIP-TURNING- MACHINE.

Application-filed August 24, 1922. Serial No. 583,993.

To all whom it may concern:

Be it known that LSIDNEY C. Wrnson, a citizen of the United States, anda resident of Rochester, in the county of Monroe and State ofNew York,have invented an Improvement in Inside Lip-Turning Machines, of whichthe following description, in connection with the accompanying drawings,is a specification, like letters on the drawings representing likeparts.

My present invention relates to shoe manufacturing machines, and moreparticularly to an inside channel laying machine.

Thepresent invention is particularly designed for usein the manufactureof boots and shoes according. to the well known Wilson process, such asis clearly shown and described in myIP-atents Nos. 1,421,3427 and1,424,74c5, dated June 27,1922, and Aug. 1, 1922,respectively. In shoesmanufactured according to the well known Wilson process, the grain sideof the insole, or that part of the insole that comes in contact with thefoot of the wearer, isprovided with a marginal channel in which thethrough and through stitching for the insole, upper, and outsole, islocated, the channel flap being in the finished shoe laid down againstthe insole, thus concealing the line of stitching and rendering theentire inner surface of the insole of the shoe smooth and preventing theobjectionable feature of having the line of stitching exposed to causeannoyance to the wearer. During the process of manufacture,

' 'and prior to the lasting of the upper'to the insolefthe channel flap,above referred to, is laid over to expose the channel and this channel,as wellas the face of the channel flap, is coated with glue. 'Heretoforethe method of operation has been to lay this channel flap down toconceal'the line of stitching by hand, and on small sizes of shoesparticularly, this has been an exceedingly zdificult operation toperformand one that it-is well nigh impossible to perform by hand. Theobject'ofmy present invention, therefore, is an improved machine for wetting themarginal channel and I channel flap and laying such flap down againstthe channelof the insole'to conceal the line of stitching.

In the accompanying drawings illustrating the preferred embodiment of myinvention:

"Fig. 1 is apla'rr view, partly in section is placed employed tosecurely fasten the drip pan 2? and wetting horn 28 to thearm 13. The

Fig.2 is a vertical longitudinal section; 4

Fig. 3 is a fragmentary View of the wetting horn, the wetting elementbeing shown in vertical longitudinal section, and

Fig. f is a vertical longitudinal section through the sediment pot.

Referring to the drawings, 10 designates a hollow base to the upper endof which is secured a hollow member 11 by bolts 12, this hollow member11 being provided with radially extending hollow arms 13and 14: re-

spectively, these arms being located at substantially right angles withrespect to each other and the space therebetween being connected by amembrane or plate 15 provided with a ledge 16 on its upper edge, theplate 15 forming a work bench. Securely attached to the top of themember 11, in any suitable manner,-is a substantially cone shaped hollowmember 17 provided, at its top end, with a plurality of upwardly andoutwardly extending arms 18, having formed integral therewith an annularplate 19. Secured to the annular plate 19, and extending above the same,is a conical heating coil 20 to the lower end of which is connected asupply pipe 21 leading to a sourceof water-supply while the upper end isconnected by pipe22 to a pipe 23, a needle valve 24 being insertedbetween the pipes22 and 23.. Beneath the heating coil 20 is a heatingelement'25, to the lower end of which 1s connected a conduit '26which'conduit 26 may lead to a source of fuel, asgas, or may be theenclosing element for Wires leading to a source of electricity,

depending on whether the heating element 25 is a gas heating element oran electrical heating element.

To the upper outer end'of the arm 13 is placed a drip pan 27 and on thisdrip pan a hollow horn '28, bolts 29 bein upper end of the wetting horn28 isformed as anelongated cup 30, in: which fits a wetting elementcomprised of a body memer 31 provided with a longitudinal groove'82 andwith achamber 33, a plurality of perforations 34 extending from thechamber '33 into the longitudinal groove 32. The lower face of'themember31 is provided witha boss 35 drilled and tappedtojreceive the upper endof a threaded pipe 36 that ex tends downwardly through the wetting horn28 and is connected to an elbow 31i the hollow arm 13. The other end ofthis elhow 37 is connected to one end of a pipe 38, the other end ofwhich is connected to an elbow 39 secured to the lower end of the pipe23. The member 31 is rather a snug fit in the elongated cup shapedmember and this member 31 is provided with a plurality of peripheralgrooves 40. The upper end of the member 31 is tapered, as shown at 41 inFig. 1. The member 31 fits into the elongated cup shaped member 30 inthe manner indicated-in Fig. 3, the lower surface of the member 31 andthe lowerinner surface of the member 30, defining a chamber adapted toreceive the water, or other fluid, that issues from the perforations 34.The used water that passes through the grooves into the chamber abovedefined, passes downwardly through the interior of the wetting horn 28and into the drip pan 27 from whence it is led by pipes 42, 43, and 44into a sediment pot 45 through a passage 46 and nipple 47 into the lowerportion of such sediment pot. Referring to Fig. 4, it will be noted thatsuch sediment pot 45 comprises an upper member 48 to the under interiorface of which is a depending member 49 in which is located the passage46, the upper end of this passage 46 being threaded at 50 to receive thelower end of the pipe 44 and the lower end of this passage beingthreaded to receive the nipple 47. The wall of the member 48 near theupper end thereof is threaded and tapped at 51 for a purpose to behereinafter described. The lower end of the member 48 is threaded at 52to receive the internally threaded member 53 formed integrally with thesediment chamber 54, this sediment chamber being provided on itsexterior with lugs 55 that are utilized when it is desired toscrew orunscrew the sediment chamber from the member 48. Located between themembers 48 and 54, and held in place both by such members and by thenipple 47, is a wire screen 56 to the peripheral edges of which, and oneach face thereof, are rubber washers or gaskets 57. Located within thebase 10 is a pump 58, the plunger 59 of which is connected by connectingrod 60 to a crank 61 secured to a shaft 62 rotatably mounted in abearing 63 formed integral, and at one side of, the base 10 and in abearing 64 formed in angular strut 65 secured in any appropriate mannerto the base 10. Tight and loose pulleys 66 and 67 respectively, aremounted on the shaft 62.

Secured to the hollow member 11 by bolts 68 is a bearing 69 on which isslidably mounted a member 70 carrying belt engaging arms 71. To theupper face of this member 70 is secured a pin 72 which is associatedwith the fork end of a lever 73, this lever 73 being pivotedintermediate its ends to a member 74 secured to the hollow member 11 bybolts 75. To the other end of this lever 74 is pivotally attached oneend of a link 76, the other end of this link being pivotally attached toa shipping lever 77 which is pivotally mounted intermediate its ends tothe lower face of the plate 15, this shipping lever being provided witha handle portion 78 located, as is evident from an inspection of Fig. 1,within convenient reach of the operator.

Connnected to the drilled and tapped hole 51 in the casing 48 of thesediment pot is a pipe 79 having a choke valve 80 and the other end ofthis pipe is connected to an elbow 81 to which is connected one end of apipe 182 that in turn is connected topipes 83 and 84 respectively, thepipe 84 being connected in the usual manner to the inlet side of thepump 58. On the outlet side of the arm 78 is a pipe 85 connected to anyconvenient source of drainage.

Mounted on the member 17 is a pilot light 86 which is preferablyconnected in the usual manner in series with an electric heating element87 that is mounted at the top of a horn 8 secured to the top outersurface of the arm 14 by bolts 89.

The operation of my improved device is as follows, assuming that it isdesired to lay down the channel flap of a shoe manufactured according tothe well known lVilson process:

The heating element 25 is started in operation, obtaining its fuelthrough the supply pipe 26 and at the same time wateris fed to theheating coil 20 through the pipe 21, the needle valve 24 being assumedto be at this time closed. Also, the heating element 87 has the currentturned on and'the fact that such current is passing through the heatingelement is indicated by the pilot lamp 86 that is in series therewith.When the water in the heating coil 20 is presumed to be hot enough, theneedle valve 24 is operated to allow the heated water to flow throughthe pipes 23, 38, and 36' into the chamber 33 from whence the waterissues practically in the form of steamthrough the perforations 34. Theshoe is placed over the elongated member 30 so that the steam arisingthrough the perforations 34 will act on the channel and open the channelflap on the interior of the shoe, softening the leather and also theglue with which the channel and channel flap are coated. From thewetting horn, the shoe is placed on to the heating element on the horn88 and the channel flap pressed and ironed down into position to closethe channel and conceal the line of stitching in the insole. The abovesequence of operations is repeated indefinitely. As the work progresses,the excess of water passes down through the V shaped passages 40 andinto the hollow arm 28, carrying with it the loose glue, leather,powder, etc., and gathers in the drip pan 27. The operator at t is stageoperates the lever 77 to. control the shipping arms 71 and move the belt(not shown) from the loose pulley 67 over onto the tight pulley 66,causing the operation of the pump 58, which pump will, by means of thepipes 84, 83, 82, and 79, draw the accumulated water from the topchamber of the sediment pot 45. As all the water drawn from suchsediment pot must first pass upward through the screen 56, it isnecessary periodically to clean such sediment pot, which is done byunscrewing the member 54, cleanin out the sediment that has collectedtherein, and replacing the ame.

While I have necessarily described the preferred embodiment of myinvention somewhat in detail, it is to be understood that I may vary thedetails of construction and arrangement of the elements described withinwide limits without departing from the spirit of the invention.
